HEATING OR COOLING APPARATUS.

SPECIFIC ATION forming part of Letters Patent No. 784,262, dated March 7, 1905.

Application filed May 2,1903- Serial No. 155,411.

To all whom it may concern.-

Be it known that 1, Jonas HEIZMANN, a subject of the Emperor of Germany, residing at Strassburg, Germany, have invented certain new and useful Improvements in Heating or Cooling Apparatus, of which the following is a specification.

My invention relates to an apparatus for transmitting heat or cold, and is more particularl y adaptedfor the transmission of heat from liquids and gases to other substances of a similar nature for heating or drying for condensing or cooling purposes.

My improved apparatus consists, essentially, of two or more relatively flat chambers each having an inlet and an outlet located at opposite ends, the chambers being so assembled that between the side walls of any two parallel chambers a hollow space is formed. Each chamber is traversed by short tubular members communicating at their ends with the said hollow spaces. Each row of transverse tubular members is displaced relatively to an adjacent row of solid transverse members, so that a substance flowing through the chamber must follow a more or less sinuous course. Any number of chambers may be superposed upon each other, the arrangement being such that the outlet of one chamber communicates directly with the inlet of the adjacent chamber, so as to compel the medium flowing through the chambers to follow a de- 'vious or Zigzag path.

My invention is illustrated by the accompanying drawings, which show one form of the apparatus.

Figure 1 is an end elevation, the top chamber being shown in section on the lineAB of Fig. 2. Fig.2 is a side elevation and part section on the line C D of Fig. 1. Fig. 3 is a plan view and part section on the line E F of Fig. 1.

(4 represents the chambers, which may be conveniently constructed of east-iron or the like, built together to form a compact battery. Each chamber has a tubular inlet-end e and a like outlet end f, the inlet 0 of one chamber always communicating directly With the outlet-f of the superposed chamber. The Walls of the chambers a are connected by rivets g and are further stayed by short transverse tubes 6, connecting the spaces '11, formed between each two parallel chambers.

m is a common supply-pipe feeding the top row of chambers to, and 3) is a like waste-pipe leading from the bottom row of chambers a.

When a liquid, steam, air, or other medium passing through the pipe m enters the top row of chambers through the inlets o, it will in order to reach the pipe 3) have to follow a zigzag downward course, as shown by the arrows, Fig. 1, owing to the disposal of the inlets and outlets efiabove described. Furthermore, owing to the rows of tubes and rivets Z) g being displaced relatively to each other the medium cannot flow in a straight line through the chamber a, but during its passage will be broken up and wash continuously against the Walls of the chambers (1, tubes 6, and rivets g. In this manner the entire surface of the apparatus is thoroughly and uniformly utilized.

I do not limit myself to the precise arrangement of rivets and tubes g 7) shown.

The chambers a. may be of various sizes and be provided with any number of tubes Z), so that the passage presented to the medium flowing through the apparatus may be increasedor descreased, as desired.

Having thus. described my invention, 1 claim A heating and cooling apparatus, consisting of a plurality of chambers each having an inlet and an outlet at opposite ends, the outlet of one chamber communicating directly with the inlet of the adjacent chamber, said chambers being assembled in parallel and spaced apart, transverse rows of short tubular members extending across each chamber, the tubular members in one chamber being directly opposite the tubular members in the adjacent chamber, transverse rows of solid members extending across each chamber and staggered with respect to the tubular members, substantially as specified.

In testimony that I claim the foregoing as my invention 1 have signed my name in presence of two subscribing witnesses.
